An imaging system for producing a panoramic radiograph of a patient’s jaw for dental analysis includes an X-ray source carried at one end of an arm and detector means at the other end. A plurality of spaced apart and transverse extending beads are formed upon the top extending surface of said beam and at least a portion of one of the front and rear surfaces are inwardly displaced relative to each other and during formation of an arcuate profile to the beam, and such that the front and rear surfaces exhibit at least partially non-parallel surfaces. Pixel coordinates are upsampled instead of pixel colors, thereby reducing computational complexity and expense. The interlayer insulating layer has a relative dielectric constant lower than that of a silicon oxide film.
